The eco 4 2.3 isn't a bad little motor but the 2.7 eco 6 would have made a lot more sense. It would have put the 2015 mustang in a better stock performance category. Like, 0-60 in 5 seconds flat and the quarter mile in 13.6. It wouldn't be faster than the coyote v8 but it would have made it a much better value. I would pay 35,000 for that but you might as well get the v8 without that option. I think we'll see it in the future. They drop the 3.7 v-6 then go with eco-4, eco-6, and the coyote v-8. Sounds good to me!!!

 

Simple, it comes down to one thing, they need some Mustang sales to include an engine that gets better fuel economy to stay inline with the governments overall CAFE (Corporate Average Fuel Economy).

Otherwise agreed, that would be a nice engine in the Mustang, just like the 3.5L EB V6 would, but both really need a rework to get more power in the upper RPM range, something the 2.3L EB I4 lacks.

 

I agree the CAFE regulations do play a major role but I think the eco 4 is a good replacement for the 3.7 v6 in regards to the CAFE regs, but they need to have something that fits between the eco 4 and the v8. I don't think the 3.7 v6 will be available much longer because of the CAFE regulations. I think we'll se an 8 speed auto tranny, soon, as well.

 

Europe is a big reason for the 4 banger being in the lineup. There's like a road tax or registration fee over there that is levied based on something like how many cylinders an engine has, so 4 cylinder engines have much less associated expense. Also gas is crazy expensive over there.

 

Fixed that for ya.


I bet driven in the real world like most Mustang owners would drive their car the 3.7 will return better overall fuel economy.

 

This. Only this. Also, some countries tax by displacement as well. 2.7 > 2.3

 

I don't think Ford should drop the eco4, I think they should drop the 3.7 v6 and use the 2.7 eco6. the eco4 would be the entry level engine.

 

Truth.


I would love to have a 2.7 EB as an option for our Mustangs. That would probably be my next engine

 

I could see that happening down the road...maybe. Depends on how the current lineup does though. Two turbo engine offerings would probably drive the Mustang upmarket even more...

 

Well, the UK (annual) tax is based on C02 emissions.......and I believe the same goes for much of Europe, although Italy was/is based on engine capacity (but it's anything over 2 liters, so even a 2.3 will be clobbered!)

Anyway, I love the idea of the 2.7, although I'd love it even more if it was a 2.8 as it'd remind me of my old 2.8 V6 Capri (European, not Mercury).

Ideally, I'd like the line-up to be:

2.3 Ecoboost 4-cylinder (310hp)
2.7 Ecoboost 6-cylinder (365hp)
5.0 Coyote 8-cylinder (450hp - with DI)
5.2 Voodoo 8-cylinder (525hp)
5.0 Ecoboost 8-cylinder (675hp - GT500)

Offer all of them with the 10-speed auto that Ford is developing with GM.

 

You have the perfect line up there, my friend!!!

 

Agreed. I could see that as one heck of a lineup.

 

Thanks gents. I'm just awaiting the call from Ford to make me product planner for Mustang

My first job will be the '17MY Mach1
